If you clear the faults do any of them show back up?


I know my FSI will show random misfires at startup while looking at live data. I've changed the spark plugs/coil packs and use top tier gas (even though it's 10% Ethanol...gripes). Still does it occasionally (mainly during warmer temps.) but only at startup. When it does the vehicle seems to exhibit a bit of a shake which goes away after 10-15 seconds and then runs smooth and gets decent gas mileage.

I thought I read somewhere that the FSI models have a tendency to do this. I've just learned to ignore it as it doesn't always shake.

Thank for response. Ive changed spark plugs and I’m I know I’m due for new coil packs. I have always noticed the rough idle/misfire during first minute or so after a cold start since I purchased with 37k. So I cleared the codes and drove it for about 9 miles or so this morning after a cold start. Did a rescan and no engine codes. I’ll rescan after a week or so see what happens.

Hi,

I have a 2011 Touareg 3.6 VR6 and experiencing multiple cylinder misfires. I have changed the plugs and coils, but still having issues intermittently. Some days not at all, then other days it's rough.

Have you had any luck figuring your issue out?

So what did u end up finding out about the fuel pump control module cause spark plugs and coils don’t cause that code

I’m getting the same code about the fuel pump control module and can’t really find anything about it I’ve found them for sale but not where it’s located and for some reason all of the vw dealers website say it’s no longer available??? Not sure why cause it’s not like my touareg is 50 yeas old

Never really did much after this scan however fast forward 11 months after post (last month) my fuel pump went out and had to be replaced.
the in-tank one or the high pressure one ? and did you replace the module ( 7p0 906 093 b) ?
i have this code popping out once in a while on mornings on startups. i also have the casual shakey vibrations until the rpm drops to operating rpm.

High pressure. No I didn't replace the module as this was not mentioned by my mechanic. I have always (since 37K miles) experienced slight shaking after a cold start up but goes away pretty quick after engine warms.
